UNITED STATES PATENT OFFICE.

THOMAS R. MoKNIG-HT, 0F AURORA, ILLINOIS, ASSIGNOR TO WESTERN WHEELEDSCRAPER COMPANY, OF AURORA, ILLINOIS, A CORPORATION OF ILLINOIS.

JOURNAL-BOX.

To all whom it may concern:

Be it known that I, Tuonns It. Mo- K'Nion'r, a citizen of the UnitedStates, residing at Aurora, in the county of Kane and State of Illinois,have invented certain new and useful Improvements in Journal-Boxes, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to journal boxes, and has for its object to providecertain improvements in the construction of the box and the covertherefor which will be hereinafter pointed out. I accomplish this objectas illustrated in the drawings and as hereinafter described.

What I regard as new is set forth in the claims.

In the drawings,-Figure 1 is a longitudinal vertical section; Fig. 2 isa plan view; Fig. 3 is an end view, part of the cover being broken away;Fig. 4 is a perspective View of the cover partly in section; and Fig. 5is a perspective view of the brass.

Referring to the drawings-43 indicates the shell of the j ournal-boxwhich is generally speaking, of the usual shape and is provided with theusual opening 7 at its outer end through which access is had to theinterior of the shell for the purpose of packing the journal. At thesides and top of the opening 7 there is an external marginal flange 8 onwhich the cover fits and slides.

9 indicates the cover, which is in the form of a plate havin a U shapedmarginal flange 10 at its sides and top forming a groove llwhichreceives the flange 8. Thus the cover may slide edgewise on the flange 8into or out of operative position. lVhen the cover is in operativeposition, as shown in Fig. 1, it is securely he c by the flange 8.

12 indicates projecting lugs carried at the sides of the cover near itslower edge, as shown in Fig. 4. Said lugs are spaced a art a distanceequal to the external width 0 the outer end of the shell so that theyfit closely against the outer sides of the shell, as shown in Fi 2.

13 indicates the journal brass, which is of the usual shape, except thatit is provided at its upper side near its front end with a Specificationof Letters Patent.

transverse rib 14, best shown in Fig. Said rib is adapted to bearagainst a shoulder 15 formed in the upper portion of the shell, as shownin Fig. 1, to limit the inward movement of the brass. Outward movementof the brass is limited by a removable key or bar 16, which is tiltedbetween lugs 17 18 provided at the opposite sides of the shell near theouter end thereof, as shown in Figs. 1 and 2. Said key is passed throughsuitable holes in the shell between said lugs, its ends projectingbeyond the sides of the shell, as shown in Fig. 2, and being secured bycotter-pins 19, or other retaining devices, as shown. Thus when thejournal is in position, the brass is held against inward movement by theshoulder 15 and against excessive outward movement by the key 16. Thekey 16 also serves to prevent accidental displacement of the cover 9 byreason of the fact that the lugs 12 project inward far enough so thatwhen the cover is moved up far enough said lugs engage the key 16 andare stopped by it before the cover leaves the flange 8, as shown indotted lines in Fig. 1. The key 16, therefore, performs the doublefunction of locking both the brass and the cover in position. Bywithdrawing the key, however, the cover may be detached and the journalbrass removed.

What I claim as my invention, and desire to secure by Letters Patent,is,-

1. A journal-box, comprising a shell having an opening at its outer end,a flange around said opening, a sliding cover-plate titted upon saidflange and having one or more inward ly-proj ecting lugs, a key carriedby the shell in position to be engaged by said lugs when the cover ismoved to a certain position, and a brass held in position by said key.

2. A journal-box, comprising a shell having an opening in its outer end,a flange around said opening, a sliding cover'plate fitted upon saidflange and having one or more inwardly projecting lugs overlying theouter surface of the sides of the shell, a removable key fittedtransversely in the shell and having its ends projecting beyond thesides thereof in the path of said lugs, and a brass having anupwardly-projecting lug,

said key lying between said lug and said opening When the parts are inoperative position.

3. A journal-box, comprising a shell, a

brass fitted therein and having an upwardly- 5 projecting lug, atransverselyextending key carried by the box in the path of said lug forholding the brass in position, a sliding cover and a lug carried by thecover and adapted to engage the key When the cover is raised to acertain extent.
